Abstract

The aim of this study was to validate the feasibility of modified frontolateral partial laryngectomy without tracheotomy using animal experiments. The glottic area before and after surgery of 6 excised canine larynges and 10 canine larynges in vivo were compared to observe whether the glottic area following modified frontolateral partial laryngectomy without tracheotomy is adequate for breathing. Significant differences were observed between the glottic areas of the excised larynges in the initial state and following modified frontolateral partial laryngectomy with the cartilage closed. However, no significant differences were observed between the glottic areas of the excised larynx in the initial state and following modified frontolateral partial laryngectomy with the cartilage open. The glottic area of the larynges in vivo in the initial state and following right chordectomy via laryngofissure were not observed to be significantly different. Furthermore, no significant differences were observed between the glottic areas of the larynges in vivo in the initial state and following modified frontolateral partial laryngectomy without tracheotomy. In conclusion, modified frontolateral partial laryngectomy without tracheotomy is a feasible and efficacious means of eradicating early and selected invasive carcinomas of the larynx, which is supported by animal experiments.
